Water heater replacement cost by type.
Installed prices for Adelphi, adjusted for local labor. Larger tanks and code upgrades move the number up.
Adelphi, Maryland, is a small community where many homes date to the 1960s. With a median home age of nearly 60 years, water heater replacement is a common need. Local installs typically range from $700–$1,700 for a tank gas unit, $750–$1,850 for electric, $1,250–$3,000+ for tankless, and $1,500–$3,400 for a heat pump model. Because Adelphi has cold winter inlet water and a humid subtropical climate, a heat pump water heater is often a strong fit, especially with the federal 25C tax credit covering 30% of the cost up to $2,000. Maryland requires a permit and inspection for any water heater replacement, and work must be done by a licensed master plumber. The final inspection checks T&P discharge, venting, and connections before the unit can be used.

Recommended unit for Adelphi
Given Maryland’s humid subtropical climate and mixed water heating, heat-pump (hybrid) is the sensible default for most Adelphi homes. Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.
